Conventions of writing style change in subtle ways with passing years--a fact that prompts the need for periodic revisions of books like this one. The authors review the fundamentals of good sentence structure and then go on to describe twenty basic sentence patterns that encompass virtually every effective way of writing sentences in English. They also draw on passages by current prominent writers, using these examples to show how varying rhythm and sentence patterns can result in elegant writing styles that keep their readers interested. Exercises with answers and explanations appear throughout the text.
